High Performance Gunning Mix With Alumina Plasticiser

CT10SG is a special calcined alumina which has high water retaining property and is ideal to add stickiness to gunning mixes. Gunning mix, or gunnite, normally refers to dry gunning process. For application the mix is transported by pressurized air to a nozzle, where the mixing water is added, and the wet mix is prayed on a surface. The process is widely used in the refractory industry for the installation of new original lining or maintenance of worn linings. Matrix slurries and laboratory test bars from the gunning mixes were investigated at Wuhan University of Science and Technology. Results are presented in this paper.
